I was wondering, may be I could have a place & follow command on the same hotkey.

/pet "Follow"
/pet "Place"

At the beginning of a fight, press it and the pet will instantly follows you (which it's already doing) and at the same time have the place icon opened on your mouse icon, then you do the place.

After the fight, click the hot key again for follow and right click your mouse to toggle the place icon.

Both actions are not on the pet's global cooldown so it should act instantly but wtih a choice on the player since Place requires a click command.
